Development and evaluation of a training model for paracentetic suprapubic cystostomy and catheterization

Minimally invasive paracentetic suprapubic cystostomy is a technique that should be learned by all surgical trainees and residents. This study aimed to develop a self-made training model for paracentetic suprapubic cystostomy and placement of the suprapubic catheter and then to evaluate its effectiveness in training fourth-year medical students.

Medical students were divided into an experimental group receiving comprehensive training involving literature, video, and model use and a control group receiving all the same training protocols as the experimental group except without hands-on practice using the model. Each student's performance was video-recorded, followed by subjective and objective evaluations by urology experts and statistical analysis.

All students completed the surgical procedures successfully. The experimental group's performance scores were significantly higher than those of the control group (median final performance scores of 91.0 vs. 86.8, respectively). Excellent scores were achieved by more students in the experimental group than in the control group (55% vs. 20%), and fewer poor scores were observed in the experimental group than in the control group (5% vs. 30%).

Based on its cost-effectiveness, reusability, and training effectiveness, this paracentetic suprapubic cystostomy training model is able to achieve goals in teaching practice quickly and easily. Use of the model should be encouraged for training senior medical students and resident physicians who may be expected to perform emergent suprapubic catheter insertion at some time.
